2024 Map of Star Valley Knoll

About this map

Owyhee River Wilderness dominates the eastern landscape of this Oregon-Idaho border region, where high-desert topography is punctuated by volcanic features like Willow Creek Butte and the prominent Star Valley Knoll. The arid terrain is navigated via isolated routes such as Tent Creek Rd and State and Co Line Rd, reflecting the remote character of Malheur and Owyhee counties. This 2024 survey documents a network of vital water management features necessary for this dry environment, including the Rabbit Run Reservoir, East Side Reservoir, and South Willow Cr Butte Reservoir. Small, ephemeral-style water bodies like Pigeon-toe Lake and the winding course of Tent Creek provide fine-scale detail for those studying the hydrology and land use along the state line.
